DETAILED DESCRIPTION

Example embodiments are described with reference to the accompanying drawings. The example embodiments may be modified in various manners.

Although the terms “first,” “second,” etc. may be used herein to describe various elements, these elements, should not be limited by these terms. These terms may be used to distinguish one element from another element. Thus, a first element may be termed a second element without departing from teachings of one or more embodiments. The description of an element as a “first” element may not require or imply the presence of a second element or other elements. The terms “first,” “second,” etc. may also be used herein to differentiate different categories or sets of elements. For conciseness, the terms “first”, “second”, etc. may represent “first-type (or first-set),” “second-type (or second-set),” etc., respectively.

In the drawings, thicknesses of layers may be illustrated in an enlarged manner for clarity and/or ease of description.

When a first element is referred to as being “on” a second element, the first element may be directly on the second element, or one or more intervening elements may be present between the first element and the second element. When a first element is referred to as being “directly on” a second element, no intended intervening elements (except for environment elements such as air) may be present between the first element and the second element.

The spatially relative terms “below”, “beneath”, “lower”, “above”, “upper” and the like, may be used herein for ease of description to describe the relations between one element and another element as illustrated in the drawings. The spatially relative terms may encompass different orientations of the device in use or operation, in addition to the orientation depicted in the drawings. For example, in the case where a device illustrated in the drawing is turned over, the device positioned “below” or “beneath” another device may be placed “above” another device. Accordingly, the illustrative term “below” may include both the lower and upper positions. The device may also be oriented in the other direction and thus the spatially relative terms may be interpreted differently depending on the orientations.

When a first element is referred to as being “connected” to a second element, the first element may be “directly connected,” “indirectly connected,” and/or “electrically connected” to the second element through one or more intervening elements.

The terms “comprises,” “including,” “includes,” and/or “including” may specify the presence of stated features, integers, steps, operations, elements, and/or components, but may not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and/or groups.

“About” or “approximately” as used herein is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, considering the measurement in question and the error associated with measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “about” may mean within one or more standard deviations, or within ±30%, 20%, 10%, 5% of the stated value.

Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by those skilled in the art to which this invention pertains. Terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an ideal or excessively formal sense unless clearly defined in the present specification.

Like reference numerals may refer to like elements.

FIG. 1 is a plan view illustrating a display device according to an embodiment.

Referring to FIG. 1, the display device includes a display panel 100, a data driver 271, a gate driver 266, a circuit board 400, a timing controller 606, and a power supply unit 605.

The display panel 100 includes a first panel 105 and a second panel 106. The first panel 105 and the second panel 106 overlap each other. The first panel 105 includes a display area 105 a and a non-display area 105 b.

The display panel 100 may be, for example, a liquid crystal display (LCD) panel or an organic light emitting diode (OLED) panel. In the case that the display panel 100 is an LCD panel, a liquid crystal layer may be disposed between the first panel 105 and the second panel 106. In the case that the display panel 100 is an OLED panel, an organic light emitting layer may be disposed between the first panel 105 and the second panel 106.

The first panel 105 includes a plurality of gate lines GL1 to GLi extending in a first direction D1, a plurality of data lines DL1 to DLj extending in a second direction D2 intersecting the first direction D1, a common line 912, and a plurality of pixels PX11 to PXij. The gate lines GL1 to GLi, the data lines, DLj and the pixels PX11 to PXij (including PX1 j and PXi1) are located on a first substrate 401 (see FIG. 4) of the first panel 105.

The second panel 106 includes a light blocking/shielding layer 476 (see FIG. 4) which defines a pixel area. In an embodiment, the light blocking layer 476 may be located on the first panel 105. The light blocking layer 476 prevents unwanted light emission.

The data lines DL1 to DLj intersect the gate lines GL1 to GLi. The data lines DL1 to DLj extend to the non-display area 105 b to be connected to the data driver 271.

The data driver 271 includes a plurality of data driving integrated circuits (“ICs”) 310_1, 310_2, . . . and 310_k. The data driving ICs 310_1, 310_2, . . . and 310_k receive digital image data signals and a data control signal applied from a timing controller 606. The data driving ICs 310_1, 310_2, . . . and 310_k sample the digital image data signals according to the data control signal, latch the sampled digital image data signals corresponding to one horizontal line in each horizontal period and apply the latched image data signals to the data lines DL1 to DLj. The data driving ICs 310_1, 310_2, . . . and 310_k may convert the digital image data signals applied from the timing controller 606 into analog image signals using a gamma voltage input from a power supply unit 605 and may apply the converted analog image signals to the data lines DL1 to DLj.

The data driving ICs 310_1, 310_2, . . . and 310_k are mounted on data carriers 320_1, 320_2, . . . and 320_k, respectively. The data carriers 320_1, 320_2, . . . and 320_k are connected between the circuit board 400 and the display panel 105. For example, each of the data carriers 320_1, 320_2, . . . and 320_k may be electrically connected between the circuit board 400 and the non-display area 105 b of the display panel 105.

The timing controller 606 and the power supply unit 605 may be disposed on the circuit board 400.

The data carriers 320_1, 320_2, . . . and 320_k include input lines for transmitting various signals applied from the timing controller 606 and the power supply unit 605 to the data driving ICs 310_1, 310_2, . . . and 310_k and include output lines for transmitting image data signals output from the data driving ICs 310_1, 310_2, . . . and 310_k to the corresponding ones of the data lines DL1 to DLj.

A data carrier at a leftmost edge, e.g., the data carrier 320_1, may include a first auxiliary line 941 and a second auxiliary line 942 for transmitting various signals and a common voltage applied from the timing controller 606 and the power supply unit 605 to the first panel 105.

A data carrier at a rightmost edge, e.g., the data carrier 320_k, may include a third auxiliary line 943 for transmitting the common voltage applied from the power supply unit 605 to the first panel 105.

The first auxiliary line 941 is connected to a gate control line 911 of the first panel 105. The gate control line 911 transmits various signals applied through the first auxiliary line 941 to the gate driver 266.

The common line 912 transmits the common voltage applied from the second and third auxiliary lines 942 and 943 to a common electrode of the second panel 106. The common line 912 may enclose three sides of the display area 105 a. The common electrode of the second panel 106 is connected to the common line 912 of the first panel 105 through a short-circuit unit (not illustrated). The common electrode receives the common voltage from the common line 912 through the short-circuit unit.

The gate control line 911 and the common line 912 may be formed in the non-display area 105 b of the first panel 105 in a line-on-glass structure.

The pixels PX11 to PXij are arranged in a matrix in the display area 105 a of the first panel 105. The pixels PX11 to PXij may include a red pixel displaying a red color, a green pixel displaying a green color, and a blue pixel displaying a blue color. In an embodiment, the red pixel, the green pixel, and the blue pixel that are adjacently disposed in a horizontal direction may define a unit pixel for displaying a unit image.

There are “j” number of pixels arranged along a p^(th) (p being one selected from 1 to i) horizontal line (hereinafter, p^(th) horizontal line pixels), which are connected to the first to j^(th) data lines DL1 to DLj, respectively. Further, the p^(th) horizontal line pixels are connected to the p^(th) gate line in common. Accordingly, the p^(th) horizontal line pixels receive a p^(th) gate signal as a common signal. That is, “j” number of pixels disposed in the same horizontal line receive the same gate signal, while pixels disposed in different horizontal lines receive different gate signals, respectively.

Each of the pixels PX11 to PXij, although not illustrated, may include a pixel transistor, a liquid crystal capacitor, and a storage capacitor. The pixel transistor is a thin film transistor, for example.

The pixel transistor is turned on according to a gate signal applied from the gate line. The turned-on pixel transistor applies the analog image data signal applied from the data line to the liquid crystal capacitor and the storage capacitor.

The liquid crystal capacitor includes a pixel electrode and a common electrode which overlap each other.

The storage capacitor includes a pixel electrode and an opposing electrode which overlap each other. Herein, the opposing electrode may be a previous gate line or a transmission line which transmits the common voltage.

The gate lines GL1 to GLi are driven by the gate driver 266 and the gate driver 266 includes a shift register.

FIG. 2 is a plan view illustrating a connection relationship between a gate control line and a gate driver of FIG. 1, and a portion of the gate control line 911 and a portion of the gate driver 266 are illustrated in FIG. 2. FIG. 3 is a view illustrating waveforms of various signals applied to the gate control line of FIG. 2 and gate signals output from the gate driver of FIG. 2, and FIG. 4 is a cross-sectional view taken along line I-I′ of FIG. 2.

Referring to FIG. 2, the gate control line 911 includes a first clock line CL1, a second clock line CL2, a third clock line CL3, a fourth clock line CL4, a fifth clock line CL5, a sixth clock line CL6, a seventh clock line CL7, an eighth clock line CL8, a base line VSL, and a start line STL.

Referring to FIG. 2 and FIG. 3, the first, second, third, fourth, fifth, sixth, seventh and eighth clock lines CL1, CL2, CL3, CL4, CL5, CL6, CL7 and CL8 transmit first, second, third, fourth, fifth, sixth, seventh and eighth clock signals CK1, CK2, CK3, CK4, CK5, CK6, CK7 and CK8, respectively, and the start line STL transmits a start vertical signal STV. The first, second, third, fourth, fifth, sixth, seventh and eighth clock signals CK1, CK2, CK3, CK4, CK5, CK6, CK7 and CK8 and the start vertical signal STV are applied from the timing controller 606. A high voltage of each of the first, second, third, fourth, fifth, sixth, seventh and eighth clock signals CK1, CK2, CK3, CK4, CK5, CK6, CK7 and CK8 corresponds to a high voltage of the gate signal.

The first, second, third, fourth, fifth, sixth, seventh and eighth clock signals CK1, CK2, CK3, CK4, CK5, CK6, CK7 and CK8 are output sequentially and in particular, are output recursively. That is, the first, second, third, fourth, fifth, sixth, seventh and eighth clock signals CK1, CK2, CK3, CK4, CK5, CK6, CK7 and CK8 are output sequentially from the first clock signal CK1 to the eighth clock signal CK8 and output once again from the first clock signal CK1 to the eighth clock signal CK8 sequentially.

High periods of the clock signals that are output in adjacent periods may overlap each other. For example, as illustrated in FIG. 3, a period corresponding to latter three fourths of a pulse width of the first clock signal CK1 and a period corresponding to former three fourths of a pulse width of the second clock signal CK2 overlap each other in time.

In addition, the fifth, sixth, seventh and eighth clock signals CK5, CK6, CK7 and CK8 have phases that are inverted, i.e., shifted by 180 degrees, with respect to the first, second, third and fourth clock signals CK1, CK2, CK3 and CK4, respectively. For example, the fifth clock signal CK5 is inverted, i.e., shifted by 180 degrees, with respect to the first clock signal CK1, the sixth clock signal CK6 is inverted, i.e., shifted by 180 degrees, with respect to the second clock signal CK2, the seventh clock signal CK7 is inverted, i.e., shifted by 180 degrees, with respect to the third clock signal CK3 and the eighth clock signal CK8 is inverted, i.e., shifted by 180 degrees, with respect to the fourth clock signal CK4.

While each of the first, second, third, fourth, fifth, sixth, seventh and eighth clock signals CK1, CK2, CK3, CK4, CK5, CK6, CK7 and CK8 is output a plurality of times in a single frame period, the start vertical signal STV is output only once in a single frame period. In other words, while each of the first, second, third, fourth, fifth, sixth, seventh and eighth clock signals CK1, CK2, CK3, CK4, CK5, CK6, CK7 and CK8 has an active state (high voltage) a plurality of times periodically in a single frame, the start vertical signal STV has an active state (high voltage) only once in a single frame period.

The gate driver 266, as illustrated in FIG. 1, is located in the non-display area 105 b of the first panel 105. The gate driver 266 includes a shift register. The shift register includes a plurality of stages ST1, ST2, ST3, ST4, ST5, ST6, ST7 and ST8.

Each of the stages ST1, ST2, ST3, ST4, ST5, ST6, ST7 and ST8 receives one of the first, second, third, fourth, fifth, sixth, seventh and eighth clock signals CK1, CK2, CK3, CK4, CK5, CK6, CK7 and CK8 to thereby generate first, second, third, fourth, fifth, sixth, seventh and eighth gate signals GS1, GS2, GS3, GS4, GS5, GS6, GS7 and GS8. An 8m+1^(th) stage (e.g., a stage ST1) receives the first clock signal CK1 to thereby generate a first gate signal GS1, an 8m+2^(th) stage (e.g., a stage ST2) receives the second clock signal CK2 to thereby generate a second gate signal GS2, an 8m+3^(th) stage (e.g., a stage ST3) receives the third clock signal CK3 to thereby generate a third gate signal GS3, an 8m+4^(th) stage (e.g., a stage ST4) receives the fourth clock signal CK4 to thereby generate a fourth gate signal GS4, an 8m+5^(th) stage (e.g., a stage ST5) receives the fifth clock signal CK5 to thereby generate a fifth gate signal GS5, an 8m+6^(th) stage (e.g., a stage ST6) receives the sixth clock signal CK6 to thereby generate a sixth gate signal GS6, an 8m+7^(th) stage (e.g., a stage ST7) receives the seventh clock signal CK7 to thereby generate a seventh gate signal GS7 and an 8m+8^(th) stage (e.g., a stage ST8) receives the eighth clock signal CK8 to thereby generate an eighth gate signal GS8. Herein, “m” is a natural number and includes 0.

Each of the stages ST1, ST2, ST3, ST4, ST5, ST6, ST7 and ST8 receives the gate signal applied from a previous stage as an initiating signal and thereby is set. The stage that is set outputs, as a gate signal, the clock signal that is applied to the corresponding stage that is set. For example, the second stage ST2 receives the first gate signal GS1 from the first stage ST1 as an initiating signal and is set. The second stage ST2 that is set receives the second clock signal CK2 and outputs the second gate signal GS2.

Although not illustrated, each of the stages ST1, ST2, ST3, ST4, ST5, ST6, ST7 and ST8 receives the gate signal applied from a succeeding stage and thereby is reset.

The first stage ST1 which is driven firstly in each frame period receives the start vertical signal STV as an initiating signal. In addition, although not illustrated, a stage that is driven lastly in each frame period also receives the start vertical signal STV. The stage that is driven lastly in each frame period receives the start vertical signal STV and thereby is reset.

As described above, the gate driver 266 may receive clock signals of eight phases, e.g., the first, second, third, fourth, fifth, sixth, seventh and eighth clock signals CK1, CK2, CK3, CK4, CK5, CK6, CK7 and CK8, but the number of phases of the clock signal is not limited thereto. That is, the gate driver 266 may receive clock signals of “q” number of phases, where “q” is a natural number greater than 1.

Referring to FIGS. 2 and 4, the first clock line CL1 is connected to the gate driver 266 through a first connection line 201 and a first conductive layer 901. For example, the first connection line 201 connects the first clock line CL1 and the first stage ST1 of the gate driver 266. The first clock line CL1 transmits the first clock signal CK1.

The display device includes a plurality of first clock members 501 extending from the first clock line CL1 and a first linking member 550 connecting the plurality of first clock members 501 to each other.
